Which of the following is a radical equation?

C.

Step-by-step explanation:

We know that,

A radical equation is the equation in which the variable is under the radical.

According to the options, we see that,

In the equation , the variable is under the radical.

All other equations have constant number under the radical.

Thus, we get,

Equation C i.e. is a radical equation.

is correct as is radical equation because the variable is under the radical and the radicand is .

Further explanation:

Radical can be describing as a square root, a cube root, a fourth root or higher root.

Radical equation can be defined as any equation that contains a radical on the variable is known as the radical equation.

The term under the radical symbol is known as radicand.

Option A is not correct.

Here, is not radical equation because the radical is on a constant term 3 not on the variable.

Option B is not correct.

Here, is not radical equation because the radical is on a constant term 3 not on the variable.

Option C is correct.

Here, is radical equation because the variable is under the radical and the radicand is  .

Option D is not correct.

Here,   is not radical equation because the variable is not under the radical.

The equation is a radical equation. Therefore is correct.

step-by-step explanation:

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3
